GGDRriedel commented 4 years ago

Same as in https://github.com/equinor/segyio/issues/421

    from segyio import _segyio

ImportError: DLL load failed: The specified module could not be found

I am on 1.9.0

Are you using conda? Windows?

jokva commented 4 years ago

For what it's worth, the segyio.dll is distributed with the conda tarball.

And the extension is importable during the build, at least:

Yes I am using conda on Windows 7 64 bit Python 3.7.5.

Oddly enough running it in a dedicated anaconda console works.

It seems to be a spyder 4.0 specific problem as it seems somewhat controversial to run relative imports from submodules.

More info perhaps here? https://stackoverflow.com/questions/16981921/relative-imports-in-python-3

Presumably you're launching Spyder from Anaconda too, right?

GGDRriedel commented 4 years ago

Yes that is correct.

I reinstalled the whole env + upgraded to Spyder , the error did not occur again.

Hi I'm using Python 3.7 on a windows 10 machine, segyio v. 1.9.1, and experience the exact same problem: File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\segyio\open.py", line 161, in open from . import _segyio ImportError: DLL load failed: The specified module could not be found.

Any suggestions on how I can work around this? Thanks
